Not a great experience with it.
I have a kobo Glo bought in Australia.
I installed 2.3.2 and it took a couple of restarts to pick it up.Even then it couldn't see any of the books on my sdcard.
So I wouldn't recommend trying it out unless you have a Japanese kobo.
The release notes btw are the same as 2.3.0
I was previously on 2.3.1 when I applied the 2.3.2 update.
Now I'm doing a factory reset and it's downloading an update..
I couldn't read my microsd card after all that, (even after the factory reset and update
)The microsd card got corrupted and the Glo reported it wasn't fat 32 anymore.
THEN I loaded the microsd card up in windows and it saw it.
I copied everything off the card and formatted it then loaded all the ebooks back on.
I didn't copy some folders called footprint, calibre and so on, only the folders and files I knew were ebooks.
Now everything is working as normal again.
Good fun! lol
